Radiocarbon dating suggests that Dynasty XVIII may have started a few years earlier than the conventional date of 1550 BC. The radiocarbon date range for its beginning is 1570–1544 BC, the mean point of which is 1557 BC.[2]

The pharaohs of Dynasty XVIII ruled for approximately two hundred and fifty years (c. 1550–1298 BC). The dates and names in the table are taken from Dodson and Hilton.[3] Many of the pharaohs were buried in the Valley of the Kings in Thebes (designated KV). More information can be found on the Theban Mapping Project website.[4] Several diplomatic marriages are known for the New Kingdom. These daughters of foreign kings are often only mentioned in cuneiform texts and are not known from other sources. The marriages were likely a way to confirm good relations between these states.[5]

Dynasty XVIII was founded by Ahmose I, the brother or son of Kamose, the last ruler of the Dynasty XVII. Ahmose finished the campaign to expel the Hyksos rulers. His reign is seen as the end of the Second Intermediate Period and the start of the New Kingdom. Ahmose was succeeded by his son, Amenhotep I, whose reign was relatively uneventful.[6]

Amenhotep I probably left no male heir and the next Pharaoh, Thutmose I, seems to have been related to the royal family through marriage. During his reign the borders of Egypt's empire reached their greatest expanse, extending in the north to Carchemish on the Euphrates and up to Kurgus beyond the fourth cataract in the south. Thutmose I was succeeded by Thutmose II and his queen, Hatshepsut. She was the daughter of Thutmose I and soon after her husband's death, ruled for over twenty years after becoming pharaoh during the minority of her stepson, who later would become pharaoh as Thutmose III.

Thutmose III who later became known as the greatest military pharaoh ever, also had a lengthy reign after becoming pharaoh. He had a second co-regency in his old age with his son Amenhotep II. Amenhotep II was succeeded by Thutmose IV, who in his turn was followed by his son Amenhotep III. The reign of Amenhotep III is seen as a high point in this dynasty. Amenhotep III undertook large scale building programmes, the extent of which can only be compared with those of the much longer reign of Ramesses II during Dynasty XIX.[7]

Amenhotep III may have shared the throne for up to 12 years with his son Amenhotep IV, who would change his name to Akhenaten. There is much debate about this proposed co-regency. Some experts believe there was a lengthy co-regency, while others prefer to see a short one. There are also many experts who believe no such co-regency existed at all.

In the fifth year of his reign Amenhotep IV changed his name to Akhenaten and moved his capital to Amarna. During the reign of Akhenaten the Aten—the sundisk—first became the most prominent deity, and eventually the Aten was considered the only god.[8] Whether this amounted to true monotheism continues to be the subject of debate within the academic community. Some state that Akhenaten created a monotheism while others point out that he merely suppressed a dominant solar cult by the assertion of another, while he never completely abandoned several other traditional deities.

Later Egyptians considered the so-called Amarna Period an unfortunate aberration. The events following Akhenaten's death are unclear. Individuals named Smenkhare and Neferneferuaten are known but their relative placement and role in history is still much debated. Tutankhamun eventually took the throne and died young.[9]

The last two members of the eighteenth dynasty—Ay and Horemheb—became rulers from the ranks of officials in the royal court, although Ay may have married the widow of Tutankhamun in order to obtain power and she did not live long afterward. Ay's reign was short. His successor was Horemheb, a general during the reign of Tutankhamun whom the childless pharaoh may have intended as his successor.[9] Horemheb may have taken the throne away from Ay in a coup. He died childless and appointed his successor, Ramesses I, who ascended the throne in 1292 BC and was the first pharaoh of the Nineteenth Dynasty.

This example to the right depicts a man named Ay who achieved the exalted religious positions of Second Prophet of Amun and High Priest of the Goddess Mut at Thebes. His career flourished during the reign of Tutankhamun, when the statue was made. The cartouches of King Ay, Tutankhamun's successor appearing on the statue, were an attempt by an artisan to "update" the sculpture.[10]

Ahmose-Nefertari. Ahmose-Nefertari was the daughter of Seqenenre Tao II, a 17th dynasty king who rose up against the Hyksos. Her brother Ahmose, expelled the Hyksos, and she became queen of a united Egypt. She was deified after she died.

Ahmose I. Though he was called the founder of the 18th dynasty, he was the brother of Kamose, the last pharaoh of the 17th dynasty. During his reign, he expelled the Hyksos from Lower Egypt and brought the Nile Delta under his control, politically unifying Egypt once again.

Amenhotep I gained the throne after his two elder brothers had died. He was the son of Ahmose and Ahmose-Nefertari. He was succeeded by Thutmose I who married his daughter, Ahmose.

Amenhotep I with his mother, Ahmose-Nefertari. Both royals are credited with opening a workmen's village at Deir el-Medina. Dier el-Medina housed the artisans and workers of the pharaohs tombs in the Valley of the Kings, from the 18th to 21st dynasties. Amenhotep I and his mother, were deified and were the village's principal gods.

Thutmose I. A military man, he came to power by marrying the sister of Amenhotep I. During his reign, he pushed the borders of Egypt into Nubia and the Levant. He is credited with the starting the building projects in what is now the temple of Karnak.

Sketch from temple relief of Thutmose II. Considered a weak ruler, he was married to his sister Hatshepsut. He named Thutmose III, his son as successor to prevent Hatshepsut from gaining the throne. They had a daughter, Neferure.

Hatshepsut. Daughter of Thutmose I, she ruled jointly as her stepson Thutmose III's co-regent. She soon took the throne for herself, and declared herself pharaoh. While there may have been other female rulers before her, she is the only one who used the symbolic beard.

Thutmosis III, a military man and member of the Thutmosid royal line is commonly called the "Napoleon of Egypt". His conquests of the Levant brought Egypt's territories and influence to its greatest extent.

Akhenaten, born Amenhotep IV, began a religious revolution in which he declared Aten was a supreme god and turned his back on the old traditions. He moved the capital to Akhetaten.

Queen Nefertiti the daughter of Ay, married Akhenaten. Her role in daily life at the court soon extended from Great Royal Wife to that of a co-regent. It is also possible that she may have ruled Egypt in her own right as pharaoh, Neferneferuaten.

Queen Meritaten, was the eldest daughter of Akhenaten and Nefertiti. She was the wife of Smenkhkare. She also may have ruled Egypt in her own right as pharaoh and is one the possible candidates of being the pharaoh, Neferneferuaten.

Neferneferure and Neferneferuaten Tasherit. Shown here as children, they were two of six daughters born to Akhenaten and Nefertiti. It is possible that Neferneferuaten Tasherit was the one who may have been her father's co-regent and may have ruled as the female pharaoh, Neferneferuaten.

Smenkhkare, was a co-regent of Akhenaten who ruled after his death. It was believed that Smenkhkare was a male guise of Nefertiti, however, it is accepted that Smenkhkare was a male. He took Meritaten, Queen Nefertiti's daughter as his wife.

Tutankhamun, formerly Tutankhaten, was Akhenaten's son. As pharaoh, he instigated policies to restore Egypt to its old religion and moved the capital away from Akhetaten.

Ay served as vizier to Akhenaten, and Tutankhamun. He was the father of Nefertiti. After the death of Tutankhamun, Ay lay a claim to the throne by burying him and marrying his granddaughter Ankhesenamun.

After the death of Ay, Horemheb assumed the throne. A commoner, he had served as vizier to both Tutankhamun and Ay. Horemheb instigated a policy of damnatio memoriae, against everyone associated with the Amarna period. He was married to Nefertiti's sister, Mutnodjmet, who died in child birth. With no heir, he appointed his own vizier, Paramessu as his successor.

Tiye was the daughter of the visizer, Yuya. She married Amenhotep III, and became his principal wife. Her knowledge of government helped her gain power in her position and she was soon running affairs of state and foreign affairs for her husband, Amenhotep III and later her son, Akhenaten. She is also Tutankhamun's grandmother.
